Q.36

Match P, Q, R and S with the appropriate numbers 1 to 6 on the right

Options:

(A) P-5, Q-1, R-6, S-2

(B) P-1, Q-2, R-3, S-4

(C) P-3, Q-4, R-5, S-1

(D) P-2, Q-6, R-1, S-3

Introduction

Matching questions based on immune cells and their functions are very common in biology and medical entrance exams. To solve such questions accurately, one must understand the specific role of each cell type in the immune system. In this article, we match Basophils, T cells, B cells, and Neutrophils with their correct biological functions and explain why only one option is correct.

Step-by-Step Matching Explanation

P) Basophils → 5 (Fc receptors for IgE)

• Basophils have Fc receptors for IgE

• They play a role in allergic reactions

✅ Correct match: P-5

Q) T Cells → 1 (Perforin)

• Cytotoxic T cells secrete perforin

• Perforin creates pores in infected or cancer cells

✅ Correct match: Q-1

R) B Cells → 6 (Plasma cells)

• B cells differentiate into plasma cells

• Plasma cells secrete antibodies

✅ Correct match: R-6

S) Neutrophils → 2 (Phagocytosis)

• Neutrophils are the first line of defense

• They perform phagocytosis of pathogens

✅ Correct match: S-2

Correct Matching Summary

P−5,  Q−1,  R−6,  S−2​

✅ Correct Answer

Option (A)

Explanation of All Options

Option (A): P-5, Q-1, R-6, S-2

✅ Correct
All immune cells are correctly matched with their known functions.

Option (B): P-1, Q-2, R-3, S-4

❌ Incorrect

• Basophils do not secrete perforin

• Albumin is not related to B cells

Option (C): P-3, Q-4, R-5, S-1

❌ Incorrect

• Albumin is synthesized in liver, not basophils

• Perforin is not produced by neutrophils

Option (D): P-2, Q-6, R-1, S-3

❌ Incorrect

• Basophils do not perform phagocytosis

• Neutrophils do not synthesize albumin
